Start at the thermostat.
Check that the thermostat is set to cooling and that the selected temperature is below the room temperature. Note any blank screen, warning, or unusual display to share with the technician. Need a tech? Phoenix Air Department, based in Tempe, offers same-day service, typically 2 to 4 hours when capacity allows: (602) 586-6001.
Notice the airflow.
Is air coming from the vents? Is the issue throughout the home or in one area? If a filter is easily and safely accessible, note whether it appears heavily loaded. These observations help the team understand the problem.
Leave equipment and electrical work to a professional.
Do not open electrical compartments, touch wiring, or repeatedly reset a breaker. If you notice smoke or a burning smell, leave the area and call emergency services when needed. If conditions indoors become unsafe, move to a cooler location.
